Abstract

The statistical analysis of our sample surveys shows us that there are many different opinions

and outcomes that come with different people taking a survey. Bar Graphs and Box and whisker

plots were used to illustrate the shapes and to compare the data between the different results of

the sample size of the surveys. The results obtained from the analysis were used to discuss the

datas sample size surveys results.

Introduction

We use statistics a lot in todays century to have a better understanding on different events and

situations. We use statistics to help us with political data and also for data regarding any

information where people are trying to find the statistics of their certain outcomes. The survey

samples are used to create an understanding of the population to help researchers have a better

understanding by creating an analysis of the data collected. The data will be examined to show

the differences and similarities between each survey taken.

Method

Participants

The participants that took place in these surveys were given a survey by students of Mr. Brian

Jeans classroom. Each student was required to have random people fill out each survey fully to

where every answer was filled in. After the student had all ten of their surveys filled out, they

were required to enter the data on a website were all the data would be collected and recorded for

the use of this project for each student, that way there would be a big enough sample size for

each student to work with.

Materials

Each person that took a survey had the same questions given to them. The people who took the

surveys can be described as materials because they were the main material which helped us

collect our data. The use of the internet was helpful in retrieving the population sample data for

the survey. Also the use of the calculator to help create graphs, solve problems, and to help find

my sample size of 60 surveys by using the calculators random integer key to get each survey

randomly.

Procedures

The first step was collecting each surveys data randomly by creating a sample size of 60 surveys

by using the calculators random integer key, randInt. This gave me my 60 random sample survey

numbers, that way I only use those surveys data only for my project. After having my sample

surveys, I went ahead and starting collecting data from sample surveys of how many males took

the survey and how many females took the survey and created a bar graph that shows the

difference between the two. Also I created a box and whisker plot by collecting the data of male

and females certain hours that they work per week. The same procedures were done with finding

the results for the Health Care Bill being passed and whether or not people think President

Obama will be reelected for president again. All it took was a little time, patience, and correct

data to be recorded.

Bar Graph for Obama to be reelected

The results for this bar graph show that the females have a bigger sample size then the men, but

the females are more in favor of President Obama not to be reelected. The males are also more in

favor of Obama not being reelected. This shows how similarities between the males and females

towards this question of the survey.

Bar Graph for Gender

The bar graph shown above shows the difference between how many males took the survey and

how many females took the survey regarding to my sample size. It shows that twenty-three males

and thirty-seven females have taken the survey out of a random sample size of sixty.

Box and Whisker Plot for (Hours of Work Per. Week)

Male n= 23 =31.6086 minX=0 Q1=20 med.=40 Q3=47 maxX=65

Female n= 37 =24.8108 minX=0 Q1=0 med=32 Q3=40 maxX=60

The box and whisker blot shown above shows that males have a greater percentage of working

more hours than females do. The females second whisker is not there because minx and Q1 are

both zero. The males did have a smaller sample size with a lot of working hours, but the women

had a lot of zeros on hours worked per week for their sample size creating their box and whisker

plot to be on lower amount of hours worked side of the graph.

Bar Graph for Results on Health Care Bill

In the bar graph shown above the males seem to be leaning more towards the undecided answer

for whether or not they agree with the health care bill being passed. The Females also seem to be

leaning for towards the undecided answer as well. In second for the females is No on the Health

Care Bill being passed, women do not agree with it. And in second place for the males the men

are barely above with No as well on the Health Care Bill being passed.

Discussion

The results of the statistical analysis showed us that there are many different opinions and

outcomes that come with different people taking a survey. The box and whisker plot

demonstrated a significant difference in male and females hours worked per week with this

sample size. The same goes for the bar graphs of results on health care bill, the bar graph for

Obama to be reelected, and the bar graph for gender. Each survey in the sample size had

different results. This shows the many different results and answers people agree upon with

certain questions relating to our current events.
